Yes, they break locks, people. They can be your best friend and your worst enemy, and can determine the outcome of a battle.

Use

To break a building lock, you simply try to enter into a locked building, and proceed with the picking project. For those that want to help you, they will have to join the picking project initiated by you (provided, of course, that they also have a crowbar). This project has a random outcome. Sometimes you break open a lock first try, and other times you are at it for days at end. Each try takes one person about a day.
